5-HTP amino acid supplements are a natural way to boost serotonin levels in the brain. Serotonin is a neurotransmitter that plays a role in mood regulation, sleep, and appetite. 5-HTP, or 5-hydroxytryptophan, is a precursor to serotonin and is derived from the amino acid tryptophan. 5-HTP supplements are often used to alleviate symptoms of depression, anxiety, and insomnia. They may also help with weight loss by reducing appetite and cravings. However, it is important to consult with a healthcare provider before taking 5-HTP supplements, especially if you are taking any medications or have a medical condition.
